Here's what I have
http://yfrog.com/f/m9a0gj/
I see that you have memcached and active record in your graph. I
don't use memcached, and am using mongoid instead of active record, so
if you pull all that out of your graph, I suppose it is the same.
One question is whether or not RPM can tell when my code is what is
churning vs when I am waiting for a response from mongodb. 7 seconds
to do this:
Controller -------
def index
page_size = params[:page_size].nil? ? 40 :
params[:page_size].to_i
respond_with(@ideas_to_rate = GiftIdea.unrated_by(get_user_id,
page_size).to_a)
end
GiftIdea ------
scope :decent, :where => {:sales_rank.lt => 1200}
scope :unrated_by, lambda {|user_id, limit|
ids_to_exclude = Rating.only(:rateable_id).where(:user_id =>
user_id).
collect{|r| r.rateable_id}
total_idea_pool = GiftIdea.total_ideas - ids_to_exclude.size -
limit
skip = total_idea_pool > 0 ? rand(total_idea_pool) : 0
Rails.logger.info("TotalIdeas: #{total_idea_pool} Skip: #{skip}
Limit: #{limit} IdeasToExclude: #{ids_to_exclude.join(',')}")
decent.not_in(:_id => ids_to_exclude).skip(skip).limit(limit)
}
seems absurd. :-)
